Application filed-February 4, 1920. Serial No. 356,313.

T 0 all whom it may concern: I

Be'it known that I, OTTO H; HUNT, a citizen of the United States,residing'at Walla Walla, in the county of Walla Walla and State oflVashington, have invented certain new and useful Improvements inClamps, of which the following is a speci fication.

This invention relates to clamping means and has for its objects toprovide a means of this class that may be cheaply constructed, that ishighly eificient, that maybe applied to irregularly contoured surfaces,and which is particularly applicable to supporting signal devices formotor vehicles.

This application expressly disclaims any and all subject matter claimedin my former patent filed February 5, 1918, and numbered 1,279,114, anddated September 17, 1918, on signal device for motor vehicles.

With the above and other objects in view reference is now had to theaccompanying drawings in which Figure 1, is a perspective view of thedevice as clamped to a figure having parallel sides; 7

Fig. 2 is a front elevation with the jaws in a straight clampingposition;

Fig. 3 is a front elevation with the aws in a distorted clampingposition; and

Fig. is a sectional view through the clamping means showing the conicalopenings.

Having reference to the drawings like numerals refer to like partsthroughout and the nume 'al 1 represents the jaw members, one of whichhas a rear portion or shoulder 2 and an extended portion 3 forming ashank and terminating in a threaded stem 4.

)n this shank is a circular disk 5 against which the signal or otherdevice may be secured by means of a nut in threaded engagement with thestem 41;

The other of said aw members carries a rear portion 6 and an inwardlyextending portion 7 of triangular form; the apex of the triangle beingpositioned against the a movable fulcrum.

of the lug permits of a greater variation in first mentioned rearportion 2 and acts as Thetr angular form T OFFICE. 1

the position of the jaws with bolts not having excessive lengths.

Both rear] portions are provided with conical openings 8, shown in Fig.1, and through these openings are the clamping bolts 9 which hold thejaws rigidly together by aid of the nuts 10. These nuts I preferconstructed with a slight shoulderl'l which willprovide a little betterseating for the nut although a standard nut 12, as shown in Fig. 1, willanswer the purpose very nicely.

In use the jaws are placed upon the or ticle to be, clamped and thebolts are tightened in the usual manner which hclds the clamp rigidly inposition.

Having thus described my invention, 1 claim.

1. Ina clamp, a pair of aw members, one of said jaw members having arear portion and an extended portion forming a shank, and terminating ina threaded stem, the

other of said jaw members having a rear portion and an inwardlyextending projecting lug, conical openings in the rear portion of bothof said jaw members, and a clamping means positioned in said conicalopenings.

and positioned-with the apex of the trian-' gle in contact with the rearportion of the first mentioned jaw member, conical openings in the rearportion of both of said jaw members, and a clamping means positioned insaid conical openings.

In testimony whereof 1 affix my signature.
